 all of a fudden over the Face of the fick Mufician, who was 

 cured by the Charms of his own Art. 



These two Inftances are quoted by the Learned Tix.Nieic- 

 wentyt, who fays, both of them (the Mufician and Dancing- 

 Mafter) were perfeftly reftored to their Senfes by Mufick. He 

 alfo obferves, that the Wound given by the 'T!arantula can only

 Tunes muft be play'd, acording to the different Nature and Co- 

 lour of thofe Tarantula s that have given the Wound *. Then

 their Underftanding : Whereupon he was lent for by the Doge,

 pracftice before him ; where, after having play'd fome time very 

 finely, (and to the Amazement of the Hearers) he at laft begun 

 a mournful Tune, with a Defign, as far as he was able, to put 

 the Doge into a melancholy Humour ; and prefently, he flruck 

 up a jovial one, to difpofe him to Mirth and Dancing ; and after 

 having repeated thefe two kind of Tunes feveral times by turns, 

 the Doge being no longer able to endure thofe different Emotions, 

 which he felt in his Soul, he was ordered to forbear playing any 

 longer. Ibid. p. 271,
